UNITED STATES PATENT OEEIcEg RAYMOND H. HORNBROOK AND WILLIAM H. WOODCOCK, OF CANTON, OHIO TRUCK FOR STREET-CARS.

SPECIFICATION forming part of Letters Patent No. 711,861, dated October 21,V 1902.

Application letl April 22, 1902.

To @ZZ whom, it may' concern:

Be it known that we, RAYMOND H. HORN- BRooK and WILLIAM H.WooDooeK, subjects of the King of Great Britain and Ireland, and residents of Canton, Ohio, have invented certain Improvements in Trucks for Street-Cars,

of which the followingis a specification.

They object of our invention to provide a strong and rigid truck intended especially for street-cars, which truck can be readily and cheaply made from ordinary merchant bars and shapes suitably bent and bolted or riveted together.

In the accompanying drawings, Figure l is a side view of a truck constructed in accordance with our invention, and Fig. 2 is a plan view of part of the same.

Each of the side sills of the truck consists of an open truss with arched upper chord, horizontal lower chord, and interposed struts, these side trusses being connected by trans-- verse angle-bars in order to produce a sti and rigidly-braced rectangular truck-frame. The arched upper chord 1 of each side truss is composed of a channel-bar bent downward at the ends, and the lower horizontal chord of the truss is in the present instance composed of two bars 2 and 3, superposed and secured together, the upper bar 2 being bent so as to form two yokes 4, the vertical legs of which constitute the pedestals for guiding the boxes 5 which receive the journals of the axles. The truss has near each end vertical struts 6 and 7 and near the center a pair of inclined struts 9, the struts 6 and 7 being secured, respectively, to the opposite vertical legs of the yokes 4 and serving as braces therefor. The struts 6 are connected to horizontal members 10, and each strut 7 is connected to one of the inclined struts 9 by means of a horizontal member 11, these horizontal members being bolted, riveted, or otherwise rigidly secured to the horizontal chord of the truss and serving to brace and stien the latter. The vertical struts and the horizontal members connected therewith consist of angle-bars bent to the proper form, the webs of these angle-bars being bent, so as to be bolted or riveted to the web of the channel-bar constituting the arched chord of the truss. The side trusses of the truck are connected together by transverse angle-bars Serial No. 104,118. (No model.)

12 atthe ends of the truck and byintermediate angle-bars 13, the vertical flanges of the end angle-bars 12 being bolted or riveted to the downwardly-bent ends of the arched chords of the side trusses and also to the upwardlybent ends of thehorizontal members 10 of the struts 6. The horizontal flanges ot' the bars l2 are boltedor riveted to the inwardly-bent ends of the bar 3 of the lower chord of the truss and also to the projecting ends of the bar 2 of the same. The vertical dan ges of the intermediate angle-bars 13 are cut away, so as to permit the horizontal ianges of said bars to overlap the channel-bars l, to which they are secured by bolts or rivets, and between these overlapping portions ot the bars 13 is interposed a plate 14, which is bolted or riveted to the channel-bar 1 and projects inwardly beyond the same, so as to provide points of attachment for the horizontal Webs of kneebraces l5,the vertical webs of which are bolted or riveted to the vertical tlanges of the angles 13, thus providing a rm and rigid connection of each of the latter to the channel-bar l.

A truck of the character described owing to its open construction is very light considering the strength which it possesses, the latter quality being due to the fact that the truck is composed almost wholly of angles and channels so connected as to be rigidly braced and stiffened, this latter feature of construction also Yreducing the cost. of the truck, since'the making ofthe same involves simply the bending and bolting or riveting together of ordinary fo'rms of merchant bars or shapes.

Having thus described our invention, we claim and desire to secure by Letters Patent- 1. A car-truck having open side trusses consisting of an arched upper chord, a horizontal lower chord, and interposed struts the Whole consisting of merchant bars or shapes bent into form and secured together, substantially as specified.

2. A car-truck having .open side trusses, each consisting of an arched upper chord and a horizontal lower chord both extending outwardly beyond the j ournal-box openings, and struts interposed between said chords, some of which are between the journal-box openings and others outwardly beyond thesame,

substantially as specified.

3. A car-truck having open side trusses,

veach comprising an arched upper chord, a

horizontal lower chord and interposed struts, the horizontal lower chord consisting of upper and lower bars secured together, the upper bar being bent to 'form yokes whose vertical legs constitute the pedestals for the journal-boxes, substantially as specified.

4. A car-truck having open side trusses, each comprising` an arched upper chord, a horizontal lower chord, and interposed struts, the lower chord being formed from two bars secured together, the upper bar having yokes forming journal-box pedestals and some of the struts constituting braces for said pedestals, each strut having a horizontal member secured to the lower chord and some of said horizontal members also serving to connect adjoining struts, substantially as specified.
